[0011] Hereinafter, embodiments of the present invention will be described with reference to the drawings.

[0012] As shown in Figure 1, in one embodiment of the present invention, the sliding structure 1 comprises one member 2, another member 3, and a sliding damper 4 provided between the one member 2 and the other member 3. In this embodiment, the sliding structure 1 is a vibration damping structure that dampens vibrations generated in the building frame 5 during earthquakes, etc., and is provided on the brace 5a of the frame 5. One member 2 is a brace piece located on one side as seen from the sliding damper 4, and the other member 3 is a brace piece located on the other side. One or both of the one member 2 and the other member 3 may be composed of a plurality of members divided in the longitudinal direction, and the plurality of members may be connected at the site where the sliding damper 4 is installed. As an example, a conceptual diagram when the other member 3 is composed of a plurality of members is shown in Figure 2. The black circles in Figure 2 indicate the connection part 5a1. Note that the sliding structure 1 is not limited to being provided on the brace 5a of the frame 5.

[0013] As shown in Fig. 3, the sliding damper 4 has a pressure contact sliding mechanism 9 in which a first one-side sliding plate 6 belonging to one member 2, an other-side sliding plate 7 belonging to the other member 3, and a second one-side sliding plate 8 belonging to one member 2 and sandwiching the other-side sliding plate 7 in the vertical direction are pressure contacted in the vertical direction and slide in the horizontal direction.

[0014] In the present embodiment, for convenience of explanation, the direction in which the sliding damper 4 slides is referred to as the horizontal direction, one side is referred to as the left side, the other side is referred to as the right side, the direction in which the first one-side sliding plate 6, the other-side sliding plate 7, and the second one-side sliding plate 8 are pressure contacted is referred to as the vertical direction, the direction from the side of the web described later toward the side of the other-side sliding plate 7 is referred to as the upper side, and the opposite side is referred to as the lower side. The horizontal direction and the vertical direction are perpendicular to each other. Also, the direction perpendicular to both the horizontal direction and the vertical direction is referred to as the front-back direction.

[0015] The sliding damper 4 is connected to a one-side attachment portion 2a belonging to one member 2 on one side (left side), and has a one-side sliding damper connection portion 10 provided with the first one-side sliding plate 6 and the second one-side sliding plate 8, and is connected to an other-side attachment portion 3a belonging to the other member 3 on the other side (right side), and has an other-side sliding damper connection portion 12 provided with the other-side sliding plate 7.

[0016] The sliding structure 1 has a first one-side joining plate 13 that connects the one-side attachment portion 2a and the one-side sliding damper connection portion 10 on the side of the first one-side sliding plate 6, a second one-side joining plate 14 that connects the one-side attachment portion 2a and the one-side sliding damper connection portion 10 on the side of the second one-side sliding plate 8, a first other-side joining plate 15 that connects the other-side attachment portion 3a and the other-side sliding damper connection portion 12 on the upper side, and a second other-side joining plate 16 that connects the other-side attachment portion 3a and the other-side sliding damper connection portion 12 on the lower side.

[0017] The sliding damper 4 has a one-side damper member 17 provided on one side (left side) to which the first one-side sliding plate 6 and the second one-side sliding plate 8 are connected, and an other-side damper member 18 provided on the other side (right side) and having the other-side sliding plate 7.

[0018] One member 2, one damper member 17, the other damper member 18, and the other member 3 are each H-shaped steel and have a web perpendicular to the front-rear direction, an upper front flange portion extending forward from the upper end of the web, an upper rear flange portion extending rearward from the upper end of the web, a lower front flange portion extending forward from the lower end of the web, and a lower rear flange portion extending rearward from the lower end of the web. However, one member 2, one damper member 17, the other damper member 18, and the other member 3 are not limited to H-shaped steel.

[0019] In this embodiment, the one-side mounting portion 2a, the first one-side joining plate 13, the second one-side joining plate 14, the one-side sliding damper connection portion 10, the first one-side sliding plate 6, the second one-side sliding plate 8, the other-side sliding plate 7, the pressure contact sliding mechanism 9, the other-side sliding damper connection portion 12, the first other-side joining plate 15, the second other-side joining plate 16, and the other-side mounting portion 3a are provided on the upper rear flange portion of one member 2, one-side damper member 17, the other-side damper member 18, and the other member 3. In this embodiment, in addition to the upper rear flange portion, a similar structure is also provided on the upper front flange portion, the lower rear flange portion, the lower front flange portion, and the web. However, it is not limited to being provided only on the web, etc.

[0020] In this embodiment, in order to reduce the labor and process of assembly at the site where the sliding damper 4 is installed, a configuration is adopted in which the sliding damper 4 is assembled in the factory, transported to the site, and connected between one member 2 and the other member 3 at the site. In this case, it is preferable to secure as much space as possible for the pressure contact sliding mechanism 9 in the sliding damper 4.

[0021] For this purpose, in the sliding structure 1 of this embodiment, the first one-side sliding plate 6 and the first one-side joining plate 13 are stacked vertically on top of each other in the one-side sliding damper connection portion 10, and the second one-side sliding plate 8 and the second one-side joining plate 14 are stacked vertically on top of each other. In other words, the one-side sliding damper connection portion 10 has an overlapping portion 10a in which the first one-side sliding plate 6, the first one-side joining plate 13, the second one-side sliding plate 8 and the second one-side joining plate 14 are stacked on top of each other.

[0022] Therefore, compared to the case shown in the comparative example in Figure 5, where the first one-side sliding plate 6 and the first one-side joining plate 13 are not overlapped in the one-side sliding damper connection part 10, and the second one-side sliding plate 8 and the second one-side joining plate 14 are not overlapped (see Figures 7A and 7B), the length of the one-side sliding damper connection part 10 in the left-right direction can be reduced, thereby increasing the space for the pressure contact sliding mechanism 9 in the sliding damper 4. Furthermore, this effect broadens the range of applicability of the construction method in which the sliding damper 4 is assembled in the factory.

[0023] In this embodiment, the one-side sliding damper connection portion 10 has an overlapping portion 10a, as well as a non-overlapping portion 10b in which the first one-side sliding plate 6 and the second one-side sliding plate 8 are overlapped on the one-side sliding damper connection portion 10, but the first one-side joining plate 13 and the second one-side joining plate 14 are not overlapped.

[0024] Therefore, as shown in Figure 4, during factory assembly, the non-overlapping portion 10b can be used to form a high-strength bolt 19 friction joint that connects to the first one-sided sliding plate 6 and the second one-sided sliding plate 8 by fastening a high-strength bolt 19 that penetrates it, thereby enabling the first one-sided sliding plate 6 and the second one-sided sliding plate 8 to be joined to the one-sided sliding damper connection portion 10. Then, on-site, when connecting the one-sided sliding damper connection portion 10 in this state to the one-sided mounting portion 2a via the first one-sided joining plate 13 and the second one-sided joining plate 14, the first one-sided joining plate 13, the first one-sided sliding plate 6, the overlapping portion 10a, the second one-sided sliding plate 8, and the second one-sided joining plate 14 can be used as a high-strength bolt 19 friction joint, as shown in Figure 3.

[0025] Furthermore, if the one-side sliding damper connection part 10 is constructed using only the overlapping part 10a without providing the non-overlapping part 10b, the factory can leave the one-side sliding damper connection part 10 (overlapping part 10a) in a state where the first one-side sliding plate 6 and the second one-side sliding plate 8 are joined by fastening temporary bolts that pass through it. At the site, the temporary bolts can be removed, the first one-side joining plate 13 and the second one-side joining plate 14 can be positioned, and the first one-side joining plate 13 and the second one-side joining plate 14 can be fastened together with permanent bolts that replace the temporary bolts.

[0026] The first one-sided joining plate 13 and the second one-sided joining plate 14 are overlapped vertically on one side of the one-sided mounting portion 2a, and the overlapping portion of the first one-sided joining plate 13, the one-sided mounting portion 2a, and the second one-sided joining plate 14 is used as a friction joint portion of a high-strength bolt 19 to connect them.

[0027] In this embodiment, filler plates 20 are provided between the one-side mounting portion 2a and the first one-side joining plate 13, and between the one-side mounting portion 2a and the second one-side joining plate 14, respectively. Filler plates 20 are also provided between the one-side sliding damper connection portion 10 and the first one-side sliding plate 6, and between the one-side sliding damper connection portion 10 and the second one-side sliding plate 8, respectively, but are not limited to this.

[0028] The first other-side connecting plate 15 and the second other-side connecting plate 16 are stacked vertically on the other-side sliding damper connection portion 12 on one side, and the stacked portion of the first other-side connecting plate 15, the other-side sliding damper connection portion 12, and the second other-side connecting plate 16 are connected by using the high-strength bolt 19 friction joint as the connection portion.

[0029] The first other-side joining plate 15 and the second other-side joining plate 16 are stacked vertically on the other-side mounting portion 3a on the other side, and the stacked portion of the first other-side joining plate 15, the other-side mounting portion 3a, and the second other-side joining plate 16 is used as a friction joint with high-strength bolts 19 to connect them.

[0030] The sliding damper 4 has a pressure-applying unit 11 that applies a pressure force to press the first sliding plate 6, the other sliding plate 7, and the second sliding plate 8 into contact. In this embodiment, the sliding damper 4 has multiple pressure-applying units 11. The number of pressure-applying units 11 provided in the sliding damper 4 can be set as appropriate and may be one or more. The pressure-applying unit 11 includes a disc spring group 11a and a fastener 11b that fastens the disc spring group 11a, the first sliding plate 6, the other sliding plate 7, and the second sliding plate 8 through in the vertical direction.

[0031] The pressure-applying unit 11, the first one-sided sliding plate 6, and the second one-sided sliding plate 8 belong to one member 2, and the other-sided sliding plate 7 belongs to the other member 3. The pressure-applying sliding mechanism 9 and the pressure-applying unit 11 dampen vibrations when the members belonging to one member 2 and the members belonging to the other member 3 move relative to each other in the left-right direction due to vibrations occurring in the frame 5, by the sliding of the first one-sided sliding plate 6, the other-sided sliding plate 7, and the second one-sided sliding plate 8 in a pressure-contact state.

[0032] In this embodiment, the pressure-contact sliding mechanism 9 has a first sliding plate 21 between the first sliding plate 6 and the other sliding plate 7, and a second sliding plate 22 between the second sliding plate 8 and the other sliding plate 7. However, the pressure-contact sliding mechanism 9 is not limited to having a configuration with a first sliding plate 21 and a second sliding plate 22.

[0033] Although embodiments of the present invention have been described above, the present invention is not limited to the embodiments described above, and the embodiments described above can be modified in various ways without departing from the spirit of the present invention.
